If you've spent much time searching through your iPhone or Android phone's respective app store and wished you could just use your friendly neighborhood Google search box, good news: Google just added iPhone and Android apps mobile search.

The bad news: It doesn't work all that well yet. Some popular apps, like Pandora's streaming radio app, showed up just like expected (I searched both "download shazam" and "shazam app") and link directly to the App Store/Market downloads. Others—including popular apps like Dropbox or TweetDeck—didn't. We'd imagine Google will work hard to improve this over time, so it's certainly a quick app search alternative worth keeping in mind.
